Explosive limit

Okay kiddo, so the explosive limit is like a really important way to measure how much gas or vapor needs to be mixed with air in order for it to explode.

Think of it like baking a cake. If you put too much flour, the cake won't rise, right? And if you don't add enough flour, the cake will turn out really weird and not taste good.

Well, explosive gases and vapors are the same. If there's too much gas or vapor in the air, it won't explode, but if there's not enough, it also won't explode.

So scientists have figured out the exact amount of gas or vapor that needs to be mixed with air for it to explode. They call this the explosive limit.

It's really important to know this because it helps keep us safe. If we know the explosive limit, we can make sure we don't accidentally mix too much gas or vapor with air and cause an explosion.

So that's the explosive limit, kiddo. It's just about figuring out the right amount of gas or vapor mixed with air so it won't explode.
